How much is a DDR1 memory module of 512MB or 1GB Thank you

I don't know what brand of memory your computer is, and I don't know if your computer is compatible with 1G. So I suggest that you buy one 512 and plug it on top of the original one, or buy two 512 ones and sell the original one, because there is a possibility that your 1G one is not compatible.

**Aspect DDR1 of 512 is about 120 to 150, last time I bought a 512DDR400 for 120 yuan, I bought it in the computer market, I am from Shanghai, that is, I bought it on Qiujiang Road.

DDR1, if you want DDR400, the general 512M manufacturers basically range from 150, 1G is 300, if it is DDR333 or lower, it is estimated that only second-hand!

DDR2 memory has a maximum of 4GB of memory, but most Gen 2 motherboards do not support a single 4GB memory. How many can be installed depends on how many your motherboard supports, and how many GB of memory you can support.

DDR2 DDR II (Double Data Rate 2) SDRAM is a next-generation memory technology standard developed by JEDEC (Joint Committee on Electronic Equipment Engineering), and the biggest difference between it and the previous generation DDR memory technology standard is that although it uses the basic method of simultaneous data transmission on the rising and falling edges of the clock, DDR2 memory has twice the pre-read capability of the previous generation DDR memory (i.e., 4-bit data read pre-fetching). In other words, DDR2 memory is capable of reading and writing data at 4 times the speed of the external bus per clock, and can run at 4 times the speed of the internal control bus.

Since the DDR2 standard stipulates that all DDR2 memory is in the form of FBGA package, unlike the widely used TSOP TSOP-package, the FBGA package can provide better electrical performance and heat dissipation, which provides a solid foundation for the stable operation of DDR2 memory and the development of future frequencies.

Recall the development of DDR, from the first generation of DDR200 applied to personal computers through DDR266, DDR333 to today's dual-channel DDR400 technology, the development of the first generation of DDR has also reached the limit of technology, and it is difficult to improve the working speed of memory through conventional methods; With the development of Intel's latest processor technology, the front-side bus has higher and higher requirements for memory bandwidth, and DDR2 memory with higher and more stable operating frequency will be the general trend.

The maximum single DDR2 memory is 4 GB

It is DDR2 800MHz 4G.

I just found a memory module with DDR2 4G.

But it's rare.

Many users who want to buy memory modules find that the performance of DDR5 is much higher than DDR4, but they don't know how it's **, in fact, DDR5** is relatively very expensive, let's take a look at the specific DDR5 memory** introduction.

1. The price of DDR5 memory under different manufacturers is different, but it is generally more than 1500 yuan.

6. And now it is still on the marketThere is no 32G4800 specification or aboveDDR5 memory modules for sale.

7. Overall, the best of all are the sameOn the expensive sideThis may be mainly related to the shortage of chips, so it is not recommended for everyone to buy DDR5 in the near future.

This DDR memory is Sharetronic brand.

The main frequency of the memory is DDR400 (PC3200).

The total memory capacity is 512M

DDR5 memory can be shipped up to 256G with a single memory this year, and it is used with the latest generation of flagship machines. Nowadays, the memory modules used in our mobile phones are DDR4, although its storage speed is already very fastBut compare the first

The memory of the mobile phone is constantly expanding, which is an inevitable trend, especially the hard disk memory is not the running memory, the hard disk memory is constantly growing, at the beginning of 200 million, and then rose to the present 256g, but now it is still the second or fourth technology, it takes multiple superpositions to achieve such an effect, and then the 5th generation has reached the effect of a single 256g, which is a very big technological progress, but whether it can adapt to it depends on the response of the market.

Buy it again in two years, it's too expensive to just go on the market, and the most important thing is that you have to have the support of software and hardware, the current 4 generations of memory can already meet the needs of office and entertainment, and there is no need to buy it on the market.

Today's 64-bit operating systems support up to 128GB of RAM, and 256GB of memory is obviously redundant.

It's definitely worth it, you can split it in half to make a RAM disk.

It depends on what you're using it for, if it's just for playing games, it's a bit overkill, but it's still necessary to update it for professional production, which varies from person to person!

I don't think you need to buy it, because now ordinary gamers don't need so much memory at all, and the ** that just came out is very high, and you can wait for two years to buy it.

I think it's still worth buying, and it's more convenient to use such a large memory.

I think it's worth buying a large memory to better improve our work efficiency, and there is no need to worry about small memory.
